Abstract :
Minimizing the work consumed by a refrigeration system is an e ective
measure for reducing the cost of products in sub-ambient chemical processes, such as
ole n plants. A recent advancement has been the introduction of mixed working
uids
in refrigeration systems in place of pure working
uids. Due to the lack of a systematic
design method for the Mixed Refrigerant Cycle (MRC), conventional approaches are largely
trial-and-error and, therefore, operations can be under far from optimal conditions. In
this paper, a novel method for systematic design of MRCs is presented, which combines
the bene ts of the thermodynamics approach and mathematical optimization. Based on
the success of the proposed systematic method for the optimal selection of refrigerant
composition and operating pressures, the method is extended to give optimal arrangement
of the cycle components. The procedure is demonstrated using a case study of the design
of MRC for a typical ole n plant.
